Advisory URL: https://access.redhat.com/errata/RHSA-2017:1101
Issue date: 2017-04-20
CVE Names: CVE-2017-5461
An update for nss is now available for Red Hat Enterprise Linux 5 Extended
Red Hat Product Security has rated this update as having a security impact
of Critical. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.
2. Relevant releases/architectures:
Red Hat Enterprise Linux Server (v. 5 ELS) - i386, s390x, x86_64
Network Security Services (NSS) is a set of libraries designed to support
the cross-platform development of security-enabled client and server
* An out-of-bounds write flaw was found in the way NSS performed certain
Base64-decoding operations. An attacker could use this flaw to create a
specially crafted certificate which, when parsed by NSS, could cause it to
crash or execute arbitrary code, using the permissions of the user running
an application compiled against the NSS library. (CVE-2017-5461)
Red Hat would like to thank the Mozilla project for reporting this issue.
Upstream acknowledges Ronald Crane as the original reporter.
For details on how to apply this update, which includes the changes
described in this advisory, refer to:
